Scientists work with animal models to better understand type 2 diabetes to treat the disease. They have developed specialized animal models that mimic the condition.  One line of mice, known as KK mice, develop obesity and glucose intolerance that lead to type 2 diabetes. Another rodent model, the Zucker diabetic fatty rat, is bred to be a precise model of human type 2 diabetes.

Research leading to almost every Nobel Prize in Medicine awarded since 1901 was dependent on data from animal models.  This fact dramatically demonstrates the important contribution animal models in biomedical research make to both international and American medical progress. In fact, since 1979, every Nobel Prize in Medicine awarded was dependent on data from animal models with the exception of the 1983 Prize awarded to Dr. Barbara McClintock for her work in plant genetics.

Protein folding and trafficking is essential for normal cell function, and when it goes awry it can lead to various chronic conditions, including fatty liver disease, diabetes, and Parkinson's. The narrative of this case study follows two undergraduate students engaged in a summer research project evaluating the effects of cell stress on cell function and health in the model organism Caenorhabditis elegans (C. elegans).  During the case study, students review animal cell organelle function and then learn about endoplasmic stress and unfolded protein response. Prior knowledge needed for the case is basic animal cell organelles and their functions and use of model organisms in research. The case was designed for a flipped classroom in which students prepare in advance by taking a quiz and watching two videos; a PowerPoint animation is also included.

FEBRUARY 20, 2015-A diverse group of experts from academia, industry and advocacy convened by a Georgetown researcher is offering recommendations to the National Institutes of Health (NIH) regarding how to address the overreliance of male cells and animals used in preclinical studies. The recommendations come as the federal research institution works to increase the inclusion of female animal models and achieve a balance in the use of male and female cells and animals in lab research.

A cornerstone of modern biomedical research is the use of mouse models to explore basic pathophysiological mechanisms, evaluate new therapeutic approaches, and make go or no-go decisions to carry new drug candidates forward into clinical trials. Systematic studies evaluating how well murine models mimic human inflammatory diseases are nonexistent. Here, we show that, although acute inflammatory stresses from different etiologies result in highly similar genomic responses in humans, the responses in corresponding mouse models correlate poorly with the human conditions and also, one another.

Lyme disease, Ebola and malaria all developed in animals before making the leap to infect humans. Predicting when such a 'zoonotic' disease will spark an outbreak remains difficult, but a new study suggests that artificial intelligence could give these efforts a boost. A computer model that incorporates machine learning can pinpoint, with 90% accuracy, rodent species that are known to harbour pathogens that can spread to humans, researchers report this week in the Proceedings of the National Academy of Sciences1. The model also identified more than 150 species that are likely to be disease reservoirs but have yet to be confirmed as such.

Recently, in an article in the New Republic, 'The Animals That Can Save Your Life', journalist Emma Young introduces readers to the emerging science of training animals to detect things humans cannot.

Hear from some of the country's leading scientists and medical experts who talk about why animal research is critical for medical progress and the advancement of both human and animal health.

The goal of RI-ITEST is to prepare diverse students for careers in information technologies by engaging them in exciting, inquiry- based learning activities that use sophisticated computational models in support of a revolutionary science curriculum. Teachers will incorporate interactive computer models developed under the Science of Atoms and Molecules (SAM) project at the Concord Consortium. These materials were specifically designed to support a deeper understanding of science made possible through interactive computer simulations and the new physics-chemistry-biology sequence. Connections will be made between the models students use to learn science and possible careers in research and industry where computer modeling is used.

Since 2003, the H5N1 influenza virus, more commonly known as the bird flu, has been responsible for the deaths of millions of chickens and ducks and has infected more than 650 people, leading to a 60 percent mortality rate for the latter. Luckily, this virus has yet to achieve human-to-human transmission, but a small number of mutations could change that, resulting in a pandemic. Now a team of investigators from St. Jude Children's Research Hospital, Stanford University Medical Center, and MacroGenics have developed an antibody which has proven 100 percent protective against the virus in two species of animal models.

The mouse is the leading organism for disease research. A rich resource of genetic variation occurs naturally in inbred and special strains owing to spontaneous mutations. However, one can also obtain desired gene mutations by using the following processes: targeted mutations that eliminate function in the whole organism or in a specific tissue; forward genetic screens using chemicals or transposons; or the introduction of exogenous transgenes as DNAs, bacterial artificial chromosomes (BACs) or reporter constructs. The mouse is the only mammal that provides such a rich resource of genetic diversity coupled with the potential for extensive genome manipulation, and is therefore a powerful application for modeling human disease.

Sure, we know insufficient serotonin levels get a bad rap when it comes to depression, but that's like blaming one person in a full-scale riot. Depression isn't caused by only one factor. In fact, study co-author Elyse Aurbach says we're probably not getting to the core of why people are depressed because "the brain is immensely complex." In this study, the research team conducted eight experiments (four on animal brains, four on brains of the deceased human kind) of varying sample sizes - from 20 to 90 brains in each - and found that the brains of deceased humans who'd been depressed had increased levels of hippocampal FGF9 and that live animals with increased FGF9 levels demonstrated depressive, anxious behavior. "This is not just a correlation," study leader Huda Akil of the University of Michigan says. Less really may be more, at least when it comes to FGF9.

The mouse is a common model used in research as a way of studying human biology and diseases, but a new study questions whether this is an accurate approach considering some stark differences - aside from many similarities - between the two species.

A dynamic 3D computer animated video takes you "inside" for a close-up look at how we're made. Watch as the mysteries of the Human Genome are literally "unraveled." 3D modeling and animation created by Bill Baker, Bakedmedia, Inc. and Mike Fisher for the National Human Genome Research Institute.

Scientists have created an "artificial womb" in the hopes of someday using the device to save babies born extremely prematurely. So far the device has only been tested on fetal lambs. A study published Tuesday involving eight animals found the device appears effective at enabling very premature fetuses to develop normally for about a month.

"There has been an over-reliance on male animals in preclinical research in the past, and as we have worked to study female specific physiological conditions, we became aware that even many aspects of our basic model of diet induced obesity are different in females," Erin Giles, assistant professor at Texas A&M University and lead author of the study, said in a press release.

Using an animal model for human PTSD, in which researchers conditioned mice to feel fear and then attempted to reverse it, the scientists found that blocking a single gene in mice could turn off their chronic fear response.

For a study published Tuesday in the journal Nature Communications, Partridge and other researchers from Philadelphia suspended premature lambs, a close animal model for human fetuses, in a liquid-filled, artificial womb, allowing them to further develop for four weeks-longer than in past similar attempts.
